Introduction

Electrification continues to be a major global trend, particularly in the automotive market. The push for CO2-neutral mobility is transforming the automotive landscape. Sales of passenger and commercial battery electric vehicles (BEV) are expected to continue to grow significantly. The rising demand for electric cars is also increasing the need for battery cells, the smallest energy storage component within the battery pack.

What CellXPro™ can do

Battery_1280x720 1

Gasket: Made from CellXPro™ materials, the main gasket creates a secure seal against external elements such as moisture, while preventing electrolyte leakage. This ensures operational reliability and supports environmental safety.

 

Seal Pin: The seal pin provides a preliminary and final closing of the electrolyte filling opening, ensuring precise control and minimizing the risk of contamination.

 

Insulator: The CellXPro™-proprietary insulator is vital for maintaining electrical isolation. It prevents contact between internal components, such as the pole and the cover, ensuring electrical safety and operational efficiency.
